Elizabeth Ferry explores how members of the Santa Fe Cooperative, a silver mine in Mexico, give meaning to their labor in an era of rampant globalization. She analyzes the cooperative's practices and the importance of patrimonio (patrimony) in their understanding of work, tradition, and community. More specifically, she argues that patrimonio, a belief that certain resources are inalienable possessions of a local collective passed down to subsequent generations, has shaped and sustained the cooperative's sense of identity.

Elizabeth Emma Ferry traces the movement of minerals as they circulate from Mexican mines to markets, museums, and private collections on both sides of the US-Mexico border. She describes how and why these byproducts of ore mining come to be valued by people in various walks of life as scientific specimens, religious offerings, works of art, and luxury collectibles. The story of mineral exploration and trade defines a variegated transnational space, shedding new light on the complex relationship between these two countries and on the process of making value itself.
